Wire Bond Electrical Structural Test Methodologies

Wire bonding, a foundational process in microelectronics, is essential for establishing a robust and low-resistance electrical connection between semiconductor chips and their respective packages or, in the case of multi-chip modules, between different chips. A connection is made from the bond pad on the chip to a corresponding pad on the package substrate or another chip through the meticulous bonding of a fine wire—usually composed of materials like gold, aluminum, or copper. This intricate process ensures the device's functionality, reliability, and overall performance. Several wire bonding testing methods have been developed and adopted to capture defects in molded integrated circuits (ICs) in microelectronics. However, the current testing methods on the market have their own strengths and weaknesses; they are not comprehensive but rather complement each other. An innovative method called capacitive testing has been developed to provide more comprehensive wire bond testing, detecting wire bond defects that are invisible with conventional testing methods. These defects include near shorts, wire sweep, wire sagging, and more.

Medical Company Increases Signal Integrity in Ultra-High Definition Endoscopy Systems

The medical landscape has dramatically transformed, with endoscopy emerging as a pivotal diagnostic tool that has revolutionized patient care. Endoscopy employs a flexible or rigid scope with a light source and camera. This diagnostic tool provides access to multiple internal organ systems, equipping healthcare providers with insight into internal anatomic structures of a person’s body for diagnostic evaluation and minimally invasive procedures such as laparoscopic surgery. This versatile procedure has expanded its reach across various organ systems, empowering healthcare providers with a comprehensive view of internal anatomic structures.A leading medical technology company specializing in endoscopy continuously produces an endoscope that delivers high-quality images for early diagnosis and minimally invasive surgery. With the advent of 4K and the impending shift to 8K imaging, the demand for high-definition video images is paramount for accurate medical procedures. The company’s R&D team had to ensure that the data transfer rate for these images exceeded 10 Gbps, a major technical hurdle. Keysight’s engineering experts recommended the high-speed digital design solutions, which comprise the Keysight Infiniium Z-Series oscilloscopes, Keysight bit error ratio testers (BERTs), Keysight vector network analyzers with time domain reflectometry (VNA-TDR), and Keysight PathWave Advanced Design System (ADS) software.
